Creator removes Flappy Bird despite making $50K/day

It's just a game. Take care of yourself first. I don't make game to ruin people lives.

This man has ethics. He doesn't care about the money. He doesn't want the money if it's gotten by providing a game that is so addictive and/or frustrating that it ruins people's lives. He grossly overestimated the self-control of gamers.
With that weight on his conscience he saw fit to remove the game.

I commend him on his morality and I wish more game devs would stand up in the name of ethics.
